Method for managing back-up power source |
摘要 |
A method for managing a back-up power source capable of maintaining the discharge capacity of a nickel metal-hydride storage battery for a long-term at a low cost, and is suitable for the management of the back-up power source for the guidance lights, the emergency lights, the information telecommunication systems, and the like is disclosed. The present invention provides a method for managing the back-up power source which uses a nickel metal-hydride storage battery including a positive electrode mainly consisting of nickel oxide, a negative electrode mainly consisting of a hydrogen storage alloy, a separator and an alkaline electrolyte, wherein an intermittent charge is performed on the nickel-metal hydride storage battery, comprising: calculating a self-discharge quantity of the nickel-metal hydride storage battery during idle period of the intermittent charge on the basis of a temperature of the nickel-metal hydride storage battery at the idling; and controlling the charging of the nickel-metal hydride storage battery on the basis of the obtained self-discharge quantities.
